Presentation

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

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

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