A028377, A028378

[Gordon Royle]

Can anyone interpret these two sequences for me please...

The description of A028378 (which arose from a search I did with 
1,2,3,5,7,9,14) is

"concatenate rows of triangle in A028377"

The description of A028377 however is the expansion of a certain 
infinite product in a single variable (presumably a generating function 
for something interesting?)

In particular, A028377 does not have a triangle.... or at least not in 
the usual sense like Pascal's triangle.

Secondly, even if A028377 is a typo and somewhere there is a triangle 
involved, what does "concatenate" mean... sum? or concatenate the 
decimal string representations of the numbers...?

Thanks

Gordon
