Presentation

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

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

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