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