Presentation

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

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

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