Presentation

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

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

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