%N Irregular array a(m,k) = A001035(k) mod m read by rows, 1<=k<=16, 3<=m.
%C Conjectures (based on mod values up to n=99): the sequence A001035(m) is (pre)periodic modulo n for all n, the lengths of the ending periods mod n (except n=4) being given by A011773 (which is related to Carmichael's lambda function).
