Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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