The millyllion is equal to \(10^{2^{1,002}} = 10^{4.2860344288 \times 10^{301}}\) in the myriad system, or 10 squared 1,002 times.[1][2] This number is comparable to ecetonplex.

In the Knuth-Pelletier -yllion system, the number is equal to 10229,626,139,054,850,904,846,566,640,235,536,396,804,463,540,417,739,040,095,528,547,365,153,252,278,474,062,771,331,897,263,301,253,983,689,192,927,797,492,554,689,423,792,172,611,066,285,186,271,233,330,637,078,259,978,290,624,560,001,377,558,296,480,089,742,857,853,980,126,972,489,563,230,927,292,776,727,894,634,052,080,932,707,941,809,993,116,324,797,617,889,259,211,246,623,299,072,328,443,940,665,362,688,337,817,968,917,011,204,758,969,615,828,117,801,869,553,000,858,005,433,413,251,661,044,016,264,472,562,583,522,535,766,634,413,197,990,792,836,254,043,559,716,808,084,319,706,366,503,081,778,867,804,183,841,109,915,567,179,344,078,320,163,914,433,261,165,510,760,851,167,452,031,056,697,572,838,864,109,017,830,551,567,765,250,350,871,057,601,645,685,541,635,930,907,524,369,702,298,058,752 or \(10^{2^{2,001}}\) (the exponent itself has 603 digits) which is equal to novemnonagintinongentimillyllion in normal -yllion system.
