Presentation

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

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

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