Hackers-on-Sea golf course is designed by the great Jack Arnold. It is a par-seventy course and its eighteen holes are all par three, four or five. The numbers of all the par-five holes are primes, and the numbers of the par-four holes are odd.
Recently I only had time to play half the course and ideally my nine consecutive holes should be par thirty-five. However, there is no such collection of holes.
What are the numbers of the par-four holes?
