Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 28 points:

(2,4)(5,6,9,11,10,7,12,8)(14,18,22,20)(16,24)(21,27,28,25)(23,26);(5,7)(6,10)(8,12)(9,11)(13,14,19,18,17,22,15,20)(16,25,26,28,24,27,23,21);(1,2,3,4)(6,7)(8,11)(13,15,17,19)(14,20,22,18)(16,23,24,26)(21,27,28,25);(5,8,12,7,10,11,9,6)(13,16,19,26,17,24,15,23)(14,21,20,27,22,28,18,25)
