  • 1. Formarly, Professor of Mathematics, Federal University of Santa Catarina, Florianópolis, SC, Brazil

Description

During past years author worked with representations of numbers in terms of 1 to 9 and 9 to 1. These representations called as crazy representations, and are done from 0 to 200000. For details see the references. This work brings natural numbers from 200001 to 220000 written in ascending and descending orders of 1 to 9 and 9 to 1. The numbers are obtained by using basic operations along with factorial.  Few numbers are by use of square-root and/or triangular numbers.
