COMMENTS
Sequence A254296 describes "feasible" partitions and gives the number of all "feasible" partitions of all natural numbers. We must take the value of m from there.
Here we list the natural numbers with the highest number of "feasible" partitions of length m. Such numbers are unique for all m except for m=[2,4,5].
For m>=6, there is a unique natural number with the maximum number of "feasible" partitions.

FORMULA
For the first 11 values, there is no specific formula.
For n>=12, a(n) = (3^(m-7)+5)/2.
Recursively, for n>=13, a(n) = 3*a(n-1)-5.
EXAMPLE
Natural numbers with maximum "feasible" partitions are unique for all m except for m=[2,4,5].
For m=1, the number 1 has 1 "feasible" partition.
For m=2, three numbers 2,3 and 4 each has the highest 1 "feasible" partition.
For m=3, the number 7 has the highest 3 "feasible" partitions.
For m=4, four numbers 16,18,19 and 22 each has the highest 12 "feasible" partitions.
For m=5, two numbers 43 and 46 each has 140 "feasible" partitions.
For m=6, the number 124 has the highest 3950 "feasible" partitions.
For m=7, the number 367 has the highest 263707 "feasible" partitions.
For m=8, the number 1096 has the highest 42285095 "feasible" partitions.
