%N Let f(h) = A141900(h) = 2^h * 3^i * 5^j * ... be the smallest term in A141586 that is divisible by 2^h but not by 2^(h+1). Sequence gives values of h where i increases.
%e Pairs (h,i) where A141900 contains a term 2^h*3^i*... for the first time, with a dash if that value of i never occurs:
%e h i
%e 0 0
