Please make a donation to keep the OEIS running. We are now in our 56th year. In the past year we added 10000 new sequences and reached almost 9000 citations (which often say "discovered thanks to the OEIS").

COMMENTS

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

LINKS

Table of n, a(n) for n=1..33.

EXAMPLE

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].

PROG

(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", "))

CROSSREFS

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