(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A134834 Let {b_n(m)} be a sequence defined by b_n(0)=1, b_n(m) = the largest prime dividing (b_n(m-1) +n). Then a(n) is the smallest positive integer such that b_n(m+a(n)) = b_n(m), for all integers m that are greater than some positive integer M. 1

Table of n, a(n) for n=1..10.

EXAMPLE

Sequence {b_9(m)} is 1,5,7,2,11,5,7,2,11,... (5,7,2,11) repeats. So a(9) = 4, the length of the cycle in {b_9(m)}.
