Paul Rapoport's comment on 72

"I'd advise anyone wanting an ET to approximate some intervals with 11 and
13 as well as the lower primes to look at 41 or 43, if said person doesn't
want 72" -P.R. (from Rick Tagawa's page)

41-tET is good; its maximum errors are 11 cents in the 11-limit and 14 cents
in the 13-limit. 43-tET is not a good option at all (it's only consistent
through the 7-limit). Much better is 46-tET, with a maximum error of 9 cents
in the 11-limit and 11 cents in the 13-limit. Then there's 58-tET, with a
maximum error of 7 cents in the 11-limit and 8 cents in the 13-limit. No
other ETs below 72 are consistent in the 13-limit without exceeding 20-cent
errors. 31-tET is consistent in the 11-limit with a maximum error of 11
cents.

72-tET has a maximum error of 4 cents in the 11-limit and 7 cents in the
13-limit.
