Presentation

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

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

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