A163352 Triangle T(n,k) = m, 0<=k<=n, read by rows, where each decimal digit d of the integer m is the maximum of the corresponding decimal digits of n and k. 1

COMMENTS

The number k is left-padded with zeros as necessary for comparison with n.

Clearly, for all n>=0, T(n,0) = T(n,n) = n.

For all A051885(n), T(A051885(n),k) = A051885(n); no other rows have constant terms.

EXAMPLE

T(10,1) = 11 = a(56) as 1>0 in both tens and units positions. Sequence first differs from A003056 here.

T(104,53) = 154 as 4>3, 5>0, and 1>0.
