## Definition

This group is defined as $B_3(3)$, the Chevalley group of type B and parameter value 3 for field:F3. Explicitly, it is the kernel of the spinor norm map from special orthogonal group:SO(7,3).

It is an example of a simple non-abelian group that is not the only simple non-abelian group of its order. There are at most two finite simple groups of any order. The other group in this case is projective symplectic group:PSp(6,3), which in the Chevalley notation is $C_3(3)$. In general, $B_n(q)$ and $C_n(q)$ have the same order, but are isomorphic only if $n = 2$ or $q$ is a prime power.

order (number of elements, equivalently, cardinality or size of underlying set) 4585351680 groups with same order As $B_m(q), m= 3, q = 3$: $q^{m^2} [\prod_{i=1}^m (q^{2i} - 1)]/\operatorname{gcd}(2,q-1)$ which becomes $3^9(3^2 - 1)(3^4 - 1)(3^6 - 1)/\operatorname{gcd}(2,2) = (19683)(8)(80)(728)/2 = 4585351680$
