In /The ATLAS of Finite Groups/ by Conway, Curtis, Norton, Parker
and Wilson, 1985 Clarendon Press, they're listed as:

O-(8,2):2 [120]
O+(8,2):2 [136]
2^7:S(6,2) [255]
2^{10}:A_8 [2295]
2^{3+8}:(S_3 x S_6) [5355]
S_3 x S(6,2) [5440]
2^{6+6}:(S_3 x L(3,2)) [11475]
S_{10} [13056]
S(4,4):2 [24192]
(S_6 x S_6):2 [45696]
L(2,17) [19353600]

where the figures in brackets are the indices in S(8,2) of the
given maximal group.
