 OFFSET 1,4 COMMENTS A hexagonal board of edge-length 3, for example, is numbered spirally as: .       17--18--19      /     16   6---7---8    /    /         \   15   5   1---2   9    \    \     /   /     14   4---3  10      \          /       13--12--11 . In Glinski's hexagonal chess, a knight (N) can move to these (o) cells: .       . . . . .      . . o o . .     . o . . . o .    . o . . . . o .   . . . . N . . . .    . o . . . . o .     . o . . . o .      . . o o . .       . . . . . . a(n) stays constant at 72085 for n >= 177 since 72085 is also the last cell visited by knight moves on a spirally numbered infinite hexagonal board, moving to the lowest unvisited cell at each step.
