Great!
I've just found it in my old files.
Congrats!
Zak

PS This is another "puzzle"
only loosely related to 185:
27, 333, 63, 234, 36 
%C all are 9k; k = 3, 37, 7, 26, 4.
%K fini, full

PPS 
A001358(60)=A117828(29)=A004148(10)=A079955(24)=A006881(54)=A119714(23)=A000712(9)=A018804(57)=A020882(29)=A020882(30)=A122618(45)=...

At all 180 cases. Anyone may wish to contribute?
