  The Rouquier blocks, also known as the RoCK blocks, are important blocks of
the symmetric groups algebras and the Hecke algebras of type A, with the
partitions labelling the Specht modules that belong to these blocks having a
particular abacus configuration. We generalise the definition of Rouquier
blocks to the Ariki-Koike algebras, where the Specht modules are indexed by
multipartitions, and explore the properties of these blocks
