%N a(n) is the number of Johnson solids of unit edge length with a volume V such that n <= V < n+1.

%C a(n) = 0 for n > 92.

%H Wikipedia, <a href="https://en.wikipedia.org/wiki/List_of_Johnson_solids">List of Johnson solids</a>

%e For n = 6: The Johnson solids with volumes V with 6 <= V < 7 are J_6, J_19 and J_23 with V ~ 6.21, 6.77 and 6.92, respectively, so a(6) = 3.

%Y Cf. A242731, A242732, A242733, A296603, A296604, A299529, A306949.
