As we know, Wales waited 64 years to reach a second World Cup. But is that the longest period between appearances on the game's biggest stage? Who else has waited as long, or is still waiting...?

Fel y gwyddwn ni, roedd Cymru'n aros ers 64 mlynedd i gyrraedd ei hail Gwpan y Byd. Ond ai hynny'r cyfnod hiraf rhwng ymddangos ar lwyfan mwyaf y gêm? Pwy arall fu aros cyhyd, neu aros o hyd....?
