If you were to lose one team, or find an extra team, then things would be perfect as you could either use
this schedule for 7 stations or the schedule for 9 stations below. But as stated the problem has no solution. You are trying to arrange 36 matches in 9 rounds with 8 stations. Each round must have 4 matches, however 4 of the stations must have 5 matches and the other 4 stations must have 4 matches (4*5 + 4*4 = 36), so there must be at least one team that has not played at each of the latter 4 stations (and also at least one team that has played twice at the former 4 stations). If a 9th station (not a bye station) is added, then all stations must have exactly 4 matches and there will be at least one team who has not played at each station (to obtain such a schedule delete all the matches involving team J below).
