Presentation

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

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

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