A fractional Friedman number is a terminating or repeating decimal that can be written in another way using its digits, the four basic arithmetic operations, exponentiation, and parentheses. Notice that a decimal point is required in the number, but not allowed in the expression to make that number. If a number can be written with its digits in order, we call it a nice fractional Friedman number and show it in red. What (nice) fractional Friedman numbers can you find?
A redundant Friedman number can be written with a subset of its digits. Given a set of digits that is not used, what is the smallest redundant Friedman number including those digits that can be written without those digits?
Here are the known terminating fractional Friedman numbers with 5 or fewer digits. The ones shown in red have the digits in the correct order. The ones smaller than 1 that use fewer than 5 digits can have any small integer added to them.

Bryce Herdt noted that redundant Friedman numbers have to use exponentiation, since that's the only way the output can have more digits than the input. Here are the smallest-known redundant Friedman numbers whose missing sets contain 2 or fewer digits.
