Presentation

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

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

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