# Proof of Sun's conjectural supercongruence involving Catalan numbers

• Received: 01 January 2020 Revised: 01 April 2020
• Primary: 11A07, 11B65; Secondary: 05A19, 33C20

• We confirm a conjectural supercongruence involving Catalan numbers, which is one of the 100 selected open conjectures on congruences of Sun. The proof makes use of hypergeometric series identities and symbolic summation method.
