=== Composite subgroups ===
=== Composite subgroups ===
If one ignores primes and focuses on integers in general, 26ed5 can instead be used as a strong tuning for the obscure [[subgroup]] '''5.6.12.22.32.34.41.44.46.49.53.56.59.63.67'''.
If one ignores primes and focuses on integers in general, 26ed5 can instead be used as a strong tuning for the giant [[subgroup]]:


One can also use any subset of that subgroup for example:
'''5.6.12.22.32.44.49.52.56.63.'''
* Only the 11-limit numbers: '''5.6.12.22.32.44.49.56.63'''
* Only numbers below 40: '''5.6.12.22.32.34'''
* Only 6 and the primes: '''5.6.41.59.67'''


==== Tables of harmonics ====
'''72.81.91.98.104.110.117.126'''
 
Or it can be a strong tuning for any smaller subgroup that is contained within that group.
 
Just some examples of possible smaller subgroups, not exhaustive:
*Only [[basis element]]s within the 50 [[integer limit]]: 5.6.12.22.32.44.49
*Only 6 and odd basis elements: 5.6.49.63.81.91.117
*Only [[7-limit]] basis elements: 5.6.12.32.49.56.63.72.81.98.126
* Only [[11-limit]] basis elements: 5.6.12.22.32.44.49.56.63.72.81.98.110.126

=== Fractional subgroups ===
===Fractional subgroups===
Fractional subgroups are another approach to taming 26ed5. One can use any of the JI ratios approximated by its individual intervals as [[basis element]]s for a subgroup.

There are dozens of possible combinations, for example the '''5.6.7/4.11/3.13/4''' subgroup, the '''5.6.7/4.9/4.9/7.11/3.13/4.13/7.13/9''' subgroup, etc.

Of all subgroup interpretations of 26ed5, be they integer or fractional, the ''60th-basis subgroup interpretation'' might be the most useful, as it includes more simple, small-numeral [[consonance]]s than any other interpretation. It includes a 6/5, 7/4, 9/4, 13/4, 11/3 and of course 5/1.
