| Mar 22, 2015 at 14:40 | comment | added | joro | I mean is it true that two symmetric matrices with 0,1 entries are similar iff their characteristic polynomials are equal? (For the general case wikipedia gives frobenius). | |

| Mar 22, 2015 at 14:05 | comment | added | joro | Thanks. Is it true that the sequence is really the OEIS sequence? | |
