%N Triangle T(n,k) read by rows, where T(n,k) = number of times the permanent of a real nonsingular n X n (0,1)-matrix takes the value k, for n >= 1, 1 <= k <= A000255(n).
%C This sequence was first provided by _Jaap Spies_.
%Y T(n, A000255(n)) = A052655(n). The n-th row of the table contains A089475(n) nonzero entries. Cf. A089479 occurrence counts for permanents of all (0, 1)-matrices, A089481 occurrence counts for permanents of singular (0, 1)-matrices.
