Presentation

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

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

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