We prove some supercongruence and divisibility results on sums involving Domb numbers, which confirm four conjectures of Z.-W. Sun and Z.-H. Sun. For instance, by using a transformation formula due to Chan and Zudilin, we show that for any prime p ≥ 5,which is regarded as a p-adic analogue of the following interesting formula for 1/π due to Rogers:Here Domb(n) and E n are the famous Domb numbers and Euler numbers.
