The sequence A009766

[Isabelle Dutour]

Hello,

I am working on a combinatorial problem that leads me to the sequence 
1; 1,1; 1,2,2; 1,3,5,5; ... (Catalan's triangle). Its
number is A009766 in the Sloane's On-Line Encyclopedia of Integer
Sequences.
I have contacted M. Meeussen (who is referenced as the sender of this
sequence) in order to get some references about it. But he has no
references.
Has anybody on this mailinglist some references about this sequence ?

Thank you in advance.
Sincerely yours.
