[seqfan] Re: An algorithm for multiplicative order of 2 mod 2n+1 (A002326)

[Richard J. Mathar]

The algorithm in http://list.seqfan.eu/pipermail/seqfan/2017-October/017983.html
seems to be closely related to the association between terminating binary
expansions and the multiplicative orders (xi, Haupt-exponent) in Cunningham's
article "on binal fractions" of 1908. The article is cited in A002326:
