'''Works with gojq, the Go implementation of jq'''
gojq provides unbounded-precision integer arithmetic and is therefore appropriate for this task.
<lang jq># To preserve precision:
def power($b): . as $in | reduce range(0;$b) as $i (1; . * $in);
range(0;22)
| . as $in
| tostring as $n
| first(range(0;infinite) as $i | 6 | power($i) | . as $p | tostring | (index($n) // empty)
| [$in,$i,$p] )</lang>
