A136348 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 divide m.

Example

Among the first 20 terms of the sequence the run of five 3's (from a(11) to a(15)) is the longest run of consecutive equal terms. (So m = 5.) Among the first 20 terms of the sequence, there are six which divide 5. (a(1),a(2),a(7),a(8),a(9),a(10)) So a(21) = 6.
