I authored A045655 back in the day.
Ostensibly, a(n) is the number of 2n-bead necklaces that are
rotationally equivalent to their reversed complements.
Clearly the description balanced is redundant, since such a necklace
must have n black and n white beads.
However, I am having difficulty generating the sequence, so it is either
incorrect, ill-described, or my programming
skills are waning.
So I am turning to the experts for help.
