I think sloane's sequences of resistor network did not include circuit #5.
Which have two type circuit # 5/1 & 5/2
N A005840 A051045
1 1 1
2 2 2
3 8 8
4 46 44
4 52 48 (Add 6 distinct circuit and 4 Possible Resistance values)
Why they excuded circuit no.5 ?
Circuit 5/1 can be modified from circuit 3 or 8
and circuit 5/2 modified from circuit 2 or 7
