| Apr 24, 2015 at 13:02 | comment | added | Adhvaitha | @Turbo Since I am interested in real multiplications, the conjectured lower bound is $7$ (from the article you referenced). | |
| Apr 24, 2015 at 13:02 | comment | added | Adhvaitha | @GerryMyerson Thanks for the reference on math.se. The paper by Turbo is useful and you are right that $7$ seems to be the conjectured lower bound over commutative rings. | |
| Apr 24, 2015 at 12:58 | comment | added | Gerry Myerson | @Turbo, it seems to me that paper claims 8 for non-commutative coefficients, but only claims at least 7 for commutative. Since OP is interested in real multiplications, we're in the commutative case here, so I'm not sure 7 is ruled out. | |

| Apr 24, 2015 at 4:19 | comment | added | Turbo | theworld.com/~sweetser/quaternions/ps/cornellcstr75-245.pdf claims magic number $8$. | |

| Apr 24, 2015 at 2:32 | comment | added | Gerry Myerson | Indeed, word-for-word duplicate. 17762, you ought to have included a link to the other question at each site. But I do note that no answers were given at the other site. | |
