わかりました、これが私が必要なことを成し遂げるための私の最初の試みです。結果にはあまり満足していませんが、うまくいっているようです。

collectedSeries.splice(j, 1); //splice out the other
break;
}
trace ("series: " + series + (i == n ? " new" : ""));
}
}
}
これにより、次の結果が得られます。
A1、G1、F1、E1、D1、C1、B1、A1
G2、A2、B2、C2、D2、E2、F2、G2
G3、A3、B3、C3、D3、E3、F3、G3
G4、A4、B4、C4、D4、E4、F4、G4
アドバイスやフィードバックをいただければ幸いです。誰もConrecを使っていない? !
編集：おっと！元の splice() にバグがありました! ごめん！現在修正済み
