This type of electric circuit is called star-delta configuration. You have two star configuration, so you can take three resistance linked by a vertex and trasform them into a delta configuration and continue until you can sum them with parallel or series addition of resistance. See this image I took from https://www.electrical4u.com/delta-star-transformation-star-delta-transformation/.
