Presentation

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

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

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