The smallest circulardigit prime formed by the concatenation
of two consecutive multidigit numbers; when 0's are added
between each number we get the smallest sixdigit number
with same property, 608609; then when the 60's are removed
we get the smallest of all, 89. [Punches]
The only compositedigit prime concatenated in order from two successive doubledigit numbers. [Loungrides]
