Presentation

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

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

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