A method and an apparatus are described for coding information, the method comprising obtaining a list of integers to be encoded; determining a hyper-pyramid having a dimension adapted to encode the list of integers, the hyper-pyramid having a plurality of vertices whose number is determined by the degree of the hyper-pyramid, which is equal to the sum of the integers of the list of integers and by the dimension of the hyper-pyramid which is equal to the number of integers of the list of integers minus one; indexing the list of integers in the hyper-pyramid using an indexing system; and providing an indication of the indexing of the list of integers in the hyper-pyramid.
