City Square

There are some markets in a city.Some of them are joined by one-way streets,such that for any market,there are exactly two street to leave out.

The city can be partitioned into \(N\) districts such that streets join only markets from different districts,and by the same one-way for any two districts.(either only from first to second,or vice-versa)

If \(N\) is a multiple of 13 and less than 2000, find the value of \(N\).
