Presentation

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

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

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