Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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