#include <bits/stdc++.h>
string c[4] = {"88", "68", "06", "16"};
int main() {
    cin >> n;
    if (n > 4) {
        cout << "Glupenky Pierre" << endl;
        return 0;
    }
    for (int i = n - 1; i >= 0; i--)
        cout << c[i] << " ";
}

"68 88" is good, isn't?

There are many more combinations. You also forgot 9
