%N A374998 Position of the last requested element when the elements of the n-th composition (in standard order) are requested from a self-organizing list initialized to (1, 2, 3, ...), using the transpose updating strategy.
%C A374998 See A374993 for details.
%F A374998 a(n) = A374993(n) - A374993(A025480(n-1)).
%F A374998 Sum_{j=1..m} a(n*2^j+2^(j-1)) = m*(m+1)/2 if m >= A333766(n). This is a consequence of the fact that the first m positions of the list are occupied by the elements 1, ..., m, as long as no element larger than m has been requested so far.
%Y A374998 Row n=1 of A375001.
%Y A374998 Analogous sequences for other updating strategies: A374997, A374999, A375000.
%Y A374998 Cf. A025480, A066099 (compositions in standard order), A333766, A374993.
