A136347 a(1)=1. Let m be the number of terms in the longest run of consecutive equal terms from among the first n terms of the sequence. a(n+1) = the number of terms, from among the first n terms of the sequence, that are coprime to m.

Example

Among the first 30 terms of the sequence the run of seven 3's (from a(23) to a(29)) is the longest run of consecutive equal terms. (So m = 7.) Among the first 30 terms of the sequence, all 30 terms are coprime to 7. So a(31) = 30.
