%N Numbers equal to the determinant of a circulant matrix based on the base-6 digits of n.

%C Base 6 variant of A219327. See A303367 .. A303369 for other bases.

%e 320 is in the sequence because 320 = 1252[6] (in base 6) and 320 = det [1,2,5,2; 2,1,2,5; 5,2,1,2; 2,5,2,1].

%o (PARI) (c(v)=abs(matdet(matrix(#v,#v,i,j,v[(j-i)%#v+1]))));for(n=1,oo,n==c(digits(n,6))&&print1(n","))

%Y Cf. A303367 (base 7), A303368 (base 8), A303369 (base 9), A219327 (base 10).
