Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

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

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