Presentation

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

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

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