Presentation

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

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

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