I delete what I added because acoustic constants are too bad comparing to those of 23edo or 26edo, and logarithmic constants don't correspond to anything mathematically

The following table shows how [[15-odd-limit intervals]] are represented in 29edo. Prime harmonics are in '''bold'''.

== Logarithmic π and ϕ, Acoustic π and ϕ ==
29edo has decent approximations of logarithmic π (4\29), [[Logarithmic phi|logarithmic ϕ]] (18\29), [[11/7#Proximity with π/2|acoustic π]] (19\29) and [[Acoustic phi|acoustic ϕ]] (20\29).<ref>octave-reduced equivalences</ref>
These intervals can be better approximated on various lower EDOs, but not all these four at the same time.

Not until [[304edo|304]] do we find a better EDO in terms of relative error on these intervals.
However, it should be noted that from a musical standpoint, only the acoustic intervals are truly relevant, and from this perspective, acoustic π and acoustic ϕ are both better represented on [[23edo]].
