Permutations of permutations

Hello,

I have the following code creating all "paths" from and to a to g and g to a which gives us 42 permutations.

library(gtools)
library(tidyverse)
x <- c(
  "a",
  "b",
  "c",
  "d",
  "e",
  "f",
  "g")

df_permutations <- gtools::permutations(n = length(x),
                                        r = 2,
                                        v = x,
                                        set = TRUE,
                                        repeats.allowed = FALSE) %>% as.data.frame()


names(df_permutations) <- c("source","target")

I now want to create permutations that vary where 2 or more permutations are selected from the created set df_permutations and all those are then listed or saved into a list object (whatever works easiest).

Thus, I should have a run where only a to b is on and one where all 42 are also selected etc. I can't seem to put in a varying value for "r" unless I loop and add it together. Is this the best way of going about this?
