Presentation

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

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

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