The sequence gives the lengths of successive segments when A280864 is split after any term s(m) where every prime divisor of s(m) has already divided s(m-1). (Then s(m+1) is the smallest number not yet in A280864 which is relatively prime to s(m).) %C A283832 See the link "Properties of A280864" in A280864 for more information. %H A283832 N. J. A.
