Presentation

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

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

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