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