Lgd.e.g.f.

[Michael Somos]

Seqfan,

I was looking at sequence A004211 and found this line :

%F A004211 E.g.f.: exp(sinh(x)*exp(x)). Lgd.e.g.f.: e^(2x).

but I have no idea what "Lgd.e.g.f." is. Probably a lot of
other people would be wondering also. It only occurrs in
OEIS in 5 sequences. What is the secret? Shalom, Michael
