In Elastica, only natural numbers less than ten thousand are known. These numbers are written down in a flexible way. The rule for Elastican numbers is as follows: each number is represented in the lowest possible base such that the resulting number have at most four digits. Unfortunately, the numbers represented in this way are not always possible to decode uniquely: For example, the four-digit Elastican number 1101 may mean 13 as well as 37. Is there a three-digit Elastican number that represents more than one natural number?
