title: Rasmussen number greater than one.
abstract: This essay describes the ramifying influence of Jens Rasmussen, illustrating how his work lives on through people whom he has influenced, even though they may have never directly collaborated. I approach this in three ways: a social network analysis of the 'Rasmussen number' (an analogue of the Erdös number); and two citations network analyses based on different search domains and different network structures.
