Well, I just found, that the eLucLeh-constant is actually
                                  4 |       __
   eLucLeh =   (2+3^0.5)^(1/4)  =  \| 2 + \|3
                                    \      \

and this (except the 4'th root) is then already mentioned in the
"formula"-segment of the A003010-sequence, noting the same logic
as mine and eLucLeh provides simply an additional shift by 2 exponents.
So I think now, even if it should be taken into OEIS, the commenting
should just link to A003010.

Fwiw ...
