Leapfrog
Leapfrog is generated by a perfect fifth and the interval class of 7 is found at +15 steps, as a double-augmented fifth (C–G𝄪). For this to work, it entails a fifth about 2–3 cents sharp of just; as a result the major third lands comfortably at a near-just 14/11 so that it can be extended to the 2.3.7.11 subgroup via tempering out 896/891. The minor third can then be identified with 13/11, tempering out 352/351 and 364/363, which implies 169/168 is tempered out as well in this case. Leapfrog is most naturally treated as such, in which it is very efficient.
A notable patent-val edo tuning not appearing in the optimal ET sequence is 80edo, which is approximately the just-13's tuning (as 10edo is used as a consistent circle of ~16/13's therein), with 13/8 still tuned slightly flat so qualifying a reasonable tuning for the 2.3.13 subgroup (as evidenced by appearing in the sequence for tetris).
Strong extensions for prime 5 include leapday (29 & 46), leapweek (46 & 63), and leapmonth (63 & 80), all of which are more complex than vanilla leapfrog. A low-complexity low-accuracy extension is given by supermean (5de & 17c), where it is merged with meantone. Srutal (46 & 80), usually considered as a strong extension of diaschismic, is a weak extension of leapfrog, and yet another weak extension is immune (29 & 63), which is in turn a strong extension of 5-limit immunity.

Temperaments with a 2.3.11 gene
Neutral
Io
Io is a very low-complexity temperament which tempers out the undecimal quartertone 33/32. This equates very different intervals (for example, the generator itself represents both 3/2 and 16/11), and as such some consider it to be an exotemperament. It has an extremely wide generator range, but the most accurate tunings are generally inside the range of flattone temperament.
The name io was coined by CompactStar in 2024 based on the color name ilo, prior to which it could only be termed as "undecimal temperament" with 33/32 being known as the undecimal comma.

Superflat
Superflat is a less inaccurate cousin of ultraflat, with less flat fifths. It tempers out 1053/1024, so 13/8 is a minor sixth, and 16/13 is a major third. Superflat and ultraflat intersect in 7edo, where major sixths and minor sixths are not distinguished.
The more accurate tunings for this temperament are generated by a fifth at least as flat as those of flattone, although often even flatter (such as 40edo's fifth). Superflat can be viewed as a 2.3.13 subgroup analogue of meantone and archy. Superflat diatonic scales have a character somewhere between neutral third scales (or mosh) and meantone diatonic scales.

Shoal
The 2.3.13.23-subgroup microtemperament is remarkable for containing not one but two superparticular intervals as small as 3888/3887 and 12168/12167. Tempering out both of them gives us this rank-2 temperament where a sharp whole tone of 26/23 is the generator, two of which stack to a 23/18 supermajor third, and eight of which stack to a 8/3 perfect eleventh. 17edo is a trivial tuning where 26/23 is equated to 9/8, tempering out the comma 208/207. More accurate tunings of shoal create a 17-note mos scale, serving as a circulating temperament of 17edo, where 208/207 is the chroma between large and small steps.

Glacier
This 2.3.13-subgroup gene is not nearly as good as shoal, but it can extend extremely well to other no-5 subgroups. It is the common restriction of bleu and navy. It is very well represented in 26edo, where a nearly pure 13/12 can serve as the generator, but 94edo provides a much better tuning.

Boethian
Boethian is a diatonic-based temperament that makes 513/512 vanish, so that the major third (C–E) is ~24/19 and the minor third (C–E♭) is ~19/16. As such, it functions as a 2.3.19-subgroup analogue of meantone, though the small size of the comma puts it at schismic level of accuracy. In particular, the equal temperaments in the tuning spectrum up to 1/2-comma (flattened) boethian temperament (very close to 12edo) are included in the schismic tuning spectrum in the 5-limit, so boethian intersects with schismic in the prime-5 infill extension thereof, called nestoria, which also tempers out 361/360, the difference between 19/18 and 20/19 or between 19/15 and 24/19.

Dog
Dog is based by 2L 5s or 7L 2s scale that makes 81/76 vanish, so 19/16 is a major third. It can be viewed as a 2.3.19-subgroup analogue of mavila.

Lipsett
Lipsett is a pleasantly melodic little temperament with a highly usable 5-tone and 9-tone mos. It is audibly similar to semaphore temperament, so it could be thought of as semaphore but for the 23rd harmonic instead of the 7th. It is named for Arthur Lipsett, the director of the Canadian short film 21-87. Leia's prison cell in Star Wars is numbered 2187, as a nod to the influence the film had on George Lucas.
