Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 6 generators on 28 points:

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