Presentation

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

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

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