Comments

An enumeration of all sorted k-tuples containing positive integers.

Begin with the 1-tuple (1), and then reading from the beginning of the list of k-tuples append to the list (n+1) if the k-tuple read is a 1-tuple and for all cases, append the (k+1)-tuples (1,n,...), (2,n,...), ..., (n,n,...), where n is the first element of the k-tuple that was read.

This sequence is a flattening of that process.

Other properties of this sequence are as A229874.
